Do not see impala app in hue after installation of impala.

I installed the cloudera manager and a small cluster. Hive through hue is working fine. Then I added the impala service. This is running fine (everything green in the cloudera manager). I want to add it now to hue so I can also run queries using impala. From what I read online, I should see the impala app under desktop/dump_config but this is not the case. I am running cloudera manager 5.13 .

When I check /run/cloudera-scm-agent/process I do notice in the hue.ini file that app_blacklist contains impala. However in the /etc/hue/conf/hue.ini file this is not the case. Also when I navigate to confiugration through cloudera manger, nothing is filled for the blacklist. WHat I understand from it , is that the app blacklist only prevents these apps listed from showing up in the standard hue web page top bar.

Maybe should I have changed something in the default configuration of impala before it is usable through hue? What does work fine is when I start the impala-shell command in Linux, so I thin impala was correctly installed.
